The exact answer would be <span>392.78
An estimated value could be either 390 or 393</span>
First you should set up fractions equal to each other to see the size ratio
8/34 = x/1.2
As to make comparable fractions. Then you would cross multiply in order to get

Divide both sides by 34 and you should get an answer of 0.28m for the model beam.
Answer:
the last one

uv
Answer:
42
Step-by-step explanation:
So if the result of it is 31,
And it is 53 less you would add back 53
53 + 31 = 84
And it is twice a number so you divide by 2 (opposite of twice a number)
84/2 = 42
The area of a circle can be calculated by formula πr^2...
radius(r)=4inches
therefore,
Area(A)=3.14×4
=12.56
